I signed my applet using self cert, and i got "UNKNOWN" publisher name.
So i want to ask if i can change this publisher name using self cert. or i have to buy a certification to get access to this parameter?

Anyone can create a self signed certificate for any name they choose and an Applet signed using the certificate and it's associated private key will show that name BUT since it is self signed the user will be prompted to accept it since the signer CA will not be in the trust store. This allows anyone to create a self-signed Applet with name, say, Oracle when it has nothing to do with Oracle.

Googling for "self signed certificate publisher" reveals this: http://stackoverflow.com/questions/6086524/how-can-i-set-the-publisher-name-in-my-signed-jar-file-using-a-self-signed-cert.
Most probably the first answer is right.
